BARREL Bertil 'r. Lindell, Detroit, Mich, assignor m The Murray Corporation of America, a corporation of Delaware Application November 6, 1933, Serial No. 696,751

6 Claims.

My invention relates to barrels and particularly to a barrel of the all-metal type having an inner and outer shell portion which are entirely insulated from each other. 5 In the copending application of C. H. Widman, A. P. Nacey and B. T. Lindell Serial No. 673,350 flled May 29, 1933, and assigned tothe assignee of the present invention, a barrel was disclosed wherein reinforcing and insulating portions were provided for supporting and sealing the inner .eontainer portion against a transfer of heat. The present invention is a further extension of the novelty of the above mentioned barrel in that the inner and outer container portions are prethe insulating material is disposed between congruous surfaces which are shaped in such manner as to provide lateral and longitudinal support at the shoulder portions of the barrel. In this manner the barrel is completely insulated except for the metal bungs where some transfer of heat will naturally occur owing to their direct contact with the contained liquid.

The chimes of the barrel are formed about laterally extending rings to provide material width to the ends of the barrel for stacking purposes and as a further assurance against slippage the ends are roughened, preferably by having the manufacturer's name embossed thereon. The barrel is reinforced at the bilge and the metal of the inner and outer container portions at the bung is joined together in a single weld to prevent the possibility of leakage between the inner and outer .container portions.

Accordingly, the main objects of my invention are; to construct a barrel of inner and outer metal containers which are entirely insulated from each other; to provide a container portion for a barrel having preformed shoulders which mate with preformed portions of the outer reinforcing elements of the barrel so as to provide complementary surfaces between which a substantially unyielding insulating material may be disposed; to provide substantially rigid insulating material between complementary surfaces of in-p her and outer container portions of a barrel which are so formed as to provide lateral and longitudinal support for the inner container portion; to provide laterally extended rings in the chime ends to form barrel ends which are fiat for stacking purposes; to emboss indlcia on the ends of the chimes to prevent slippage when stacked and in general, to construct a barrel of the all-metal, insulated type which is simple in construction, which is rugged and which is economical of manufacture.

Other objects and features of novelty of my invention will be either specifically pointed out or will become apparent when referring, for a better understanding of my invention, to the formed in such manner that when joined together following description taken in conjunction with the accompanying drawing, wherein:

Figure 1 is a broken view, partially in section and partly in elevation, of a barrel embodying features of my invention,

Fig. 2 is an enlarged broken sectional view of the structure illustrated in Fig. 1,

Fig. 3 is a view of structure similar to that illustrated in Fig. 2, showing a modified form there-'- of, and

Fig. 4 is a reduced plan view of the structure illustrated in Fig. l.

The metal barrel herein illustrated and described somewhat follows the construction illustrated and described in the above mentioned copending application. The inner container portions ID are of similar construction being stamped from the samedies to have the reversely bent shoulder portions Ii therein by which the innercontainer portions are supported against lateral or longitudinal movement. One of the container portions III has a central hole formed therein, the metal being flanged in Z-shape, as at i2, illustrated in Fig. 1. A collar I3 is mated therewith and flanged over at It and preferably brazed or otherwise secured to the marginal edge of the Z-shaped marginal flange i2. A thread I5 is provided on the collar l3 in which a tap-bung I6 is secured. The two portions l0 are mated together at the bilge and are secured in unit construction by a welding operation at H, as illustrated in Figs. 1, 2 and 3.

Like reinforcing outer portions i 8 are of pot shape having pressed-in end portions I9 which are further preformed at 2| to form a deep chime groove and a reversely curved surface 22 which is similar in shape to the curved surface ii, the purpose of which will be explained more fully hereinafter. A semi-circular bung opening 23 is provided in each one of the container portions l0 and the reinforcing portions l8. A central opening 24 is provided in the end iii of one of the portions l8 having an outward flange 25 on the edge thereof which mates with the flange 26 provided on the edge of the Z-shaped flange l2 of the inner container portion i0. Before assem-' bly a reinforcing belt 21 is secured to one of the reinforcing portions preferably by welding at 28 and a bung 29 is brazed or otherwise secured to the outwardly directed flange 3i at the margin of the semi-circular openings 23 in each one of the liquid containing portions I0.

An annular insulating ring 32 is placed over the surface 22 as illustrated in Fig. 1 and the inner container portions l0 after being secured together are set within the lower reinforcing portion i 8. An upper insulating ring is then placed on the top of the container portion l0 and the upper reinforcing portion I8 is disposed over the belt 28 and is forced down into a position to abut against the edge of the bottom reinforcing portion I8. The two portions are then welded together at 33 to form the complete construction.

Annular reinforcing portions are provided for the chimes 34 of the barrel, the ring portion 35 being made from a bar of greater width than thickness and is formed into ring shape on the greater dimension to provide width to the chime end. The metal is pressed about the ring at the end of the chimes, as illustrated in the Fig. 1. Preferably, before the rolling operation the name of the manufacturer or other indicia 36 is formed on the end surface of the chime for the purpose of roughening the surface to prevent the slippage of the barrels when one is stacked upon another.

A suitable insulating material 31 may be provided between the inner container portions l0 and the outer reinforcing portions l8 of the barrel before assembly, as illustrated in Fig. 1, to increase the insulating qualities of the barrel against the transfer of heat.

The employment of the insulating material 32,

which is preferably non-compressible, between the surfaces II and 22 of the inner and outer container portions i0 and i8, provides a support for the inner container portion against both lateral and longitudinal shifting so that the inner container portion is entirely insulated at the supporting portion which rigidly retains the inner portion against movement relative thereto.

The flanges 24 and 26 of the inner container portions l0 and the outer container portions l8 are adjacent to the collar l3 and are welded together to form a unit construction. This prevents a leak, which may occur between the collar and the inner container portions 10, from passing liquid between the inner container portions l0 and the outer reinforcing portions l8 .of the barrel.

Before the tap bung I6 is screwed into the collar I3 a name plate 38 may be disposed over the head IQ of the barrel. The name plate is provided with an opening in the center over which the shoulders of the bung l6 extend and force the name plate into firm fixed relation to the head I9 of the barrel. The edges of the name plate 38 may be spot welded or otherwise secured at the outer edges to the head IQ of the barrel. A government stamp retainer plate 39 may be flanged over the tap-bung I 6.

As a further extension of my invention I have illustrated in Fig. 3 the reinforcing band 21 as being divided into portions 40 and 4|. The portion 40 is similar to portion 4| with the exception that an extending flange 42 is provided having an inturned end portion 43 which acts as a guide for the end 44 of the outer reinforcing portions N3 of the barrel. The end portion 43 guides and positions the ends 44 relative to each other so that they will be in aligned relation when welded. In this manner the two reinforcing portions 40 and 4| are welded to the bilge portions or end portions of the reinforcing portions l8 of the barrel and one portion press fitted over the extending end 43 to have its end guidecl into abutted relation and retained therein during the welding operation.

The barrel thus constructed is entirely insulated except for the metal bungs which contact the liquid within the barrel and is completely reinforced at the bilge and chime portions to provide strength and to prevent distortion and damage. The inner container portion is supported by the outer container portion through congruent surfaces which engage an insulating material in such manner as to provide both lateral and longitudinal support to the inner container portion. The chime ends are made wide to provide stacking surfaces which may be roughened by embossing indicia to insure against slippage when stacked.

While I have described and illustrated but a single embodiment of my invention, it will be apparent to those skilled in the art that various changes, omissions, additions and substitutions may be made therein without departing from the spirit and scope .of my invention as set forth in the accompanying claims.

I claim as my invention:
